COTTON-GIN.'

SPECIFICATION forming part of Letters Patent No. 260,660, dated July 4, 1882. Application mea July 16,1881. (No model.) l

Y To all whom tt may concern:

Be it known that I, JOSEPH E. CARVER, o Bridgewater,`in theL county of Plymouth and State of Massachusetts, have invented a new and useful Improvement in Cotton-Gins, of which the following is a specification.

. The object of my invention is to provide a means for adjusting the seed-board in a cottongin, so that it may be quickly and certainly adj usted by one person, and,what is of great importance, effecting the adjustment while the machine is in operation, and so that the result can readily be seen by the person so adjusting.

Cotton-gins -known as hulling-gins, designed for ginning hully cotton, are provided withtwo roll-boxes, one within the other-the outer box for separating the hulls and the in-Y ner one for separating the seed from the cotton in the usual manner. Their capacity for ginning depends much on the character of the cotton. If gathered with all the hulls and stems, sufficient cottoncannot be carried to the inner roll-box to form a large roll.

The objection to the method of adjustment in common use is that two meu are required to move the seed board, one at each end, often requiring hours to adjust the same properly. By means of my improvement these objections are overcome, and the adjustment of the seed-board is effected by one person and in a very short time by means hereinafter fully set forth.

Referring to the accompanying drawings, Figurel is a vertical section of a machine embodying my invention. Fig. 2 is a vertical section ofthe seed-board, showin g my improved means of adjustment. Fig. 3 is a front View of the holdin g-iron and adj usting-Screw. Fig.

Eig. 5 is To each end of' thel seed-board, where it iscon'nected to the head A, I attach a holdingiron, G, each having a flange, G', extending an inch or morein frontof the said seed-board, as indicated in Figs. 2, 3, and 5. On the inner or curved side of the edge of the seedboard E is secured a metal strap, H, for the purpose of strengthening the same.y

To fasten the holding-irons, a thumb-screw, I, is passed through the lower slot, F', in the roll-box head into a screw-hole, K, at the lower part of the holding-iron G. (See Fig. 4.) This allows ofa lateral movement of the seed-board without permitting it to drop. Near the upper end of the holding-iron is a recessed slot, L, in which is arranged a sliding nut, M, Fig. 4.- A thumbscrew, N, passes through the upper horizontal slot, F, Fig. 2,`

in the roll-box head A into the sliding nut M. This arrangement admits of the adjustment of the top and bottom oi' the seed-board in either direction.

In the flange G of theholding-iron is avertical slot, O, Fig. 3, in which is itted so as to move freely a pin having a screw-threaded eye, P, with shoulders bearing upon the sides of the slot O, the pin passing through the slot and being secured to the seed-board, through which it also passes, `by means of a nut, P', Fig. 2.

A thumb-screw, Q, supported in arms or projections R It on the holding-iron G, passes through the head or eye P. By turning the T when the seed-board E is properly adjusted the latter is firmly held in position.

What I claim as my invention ise- 1. The combination, with the seed-board E, of the holdin g-irons G, constructed with flan ges G', extending up the sides of the seed-board, provided with slots, pins having screw-thread- IOO ed eyes P and nuts 1?',und the thumbscreWsQ, In testimony whereof I have signed my name ro supported in projections RR on the hoidingto this specification in the presence of two subirons G, substantially as shown and described. soribing witnesses.
